Popis: Using a novel method employing a V8 protease digestion coupled with ethyl acetate extraction, we have purified a peptide with C-terminal amide structure from porcine cardiac atrium. The peptide was determined to be Ala-Val-Leu-Gly-Leu-CONH2. According to the sequence, we have raised an antibody and established the radioimmunoassay. Using this radioimmunoassay, we have isolated a novel 14 amino acid peptide where C-terminus was amidated. This peptide was termed amidicin. Amidicin is widely distributed in porcine tissue and is especially abundant in pituitary gland, cardiac ventricle, and spleen.
